CLINTON R. WEBBER AND GEORGE W. BLOOD, OF SPOKANE, WASHINGTON.

HOOP FOR TANKS.

i .e'rniee.

To all whom it may concern:

Be it known that we, CLINTON R. WEBBER and Gnonon lV. BLOOD, citizens of the United States, residing at Spokane, in the county of Spokane and State of Washington, have inented certain new and useful Improvements in Hoops for Tanks; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to hoops for tanks and the like andv has for an object to provide means for exerting tension upon hoops, the said tension means being disposed within the peripheral surface of the tank.

A further object of the invention is to provide a. tank built up of staves having cluunbers formed in the periphery of such staves at the required points, with hoops embracing the tank having inturned ex tremities located within the chambers, and tension means also located within the chambers and engaging the inturned ends.

A further object of the invention is to provide improved means for closing and covering the chambers formed in the staves.

-With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

in the drawings :Figure 1 is a view taken transversely to a single stave, showing a chamber formed therein and the inturned extremities of the embracing hoops. Fig. 2 is a perspective view of one of the inturned hoop extremities. Fig. 3 is a view in side elevation of a circular tank or drum provided with the present invention. Fig. 4 is a perspective view of one of the chamber covers.

Like characters of reference indicate cor responding parts throughout the several views.

It is well known that in the ordinary practice of hooping tanks the ends are turned outwardly and tension screws or bolts inserted through such outwardly turned ends. For stationary tanks such con struction has few objectionable features but for rotating tanks such as washers or the like, accidents result from such outturned ends catching clothing of operatives, and in other ways. The present invention involves Specification of Letters Patent.

Serial No. 678,083.

a means for producing the tension effect upon the hoops embracing the stave structure of the tank without having the ends extend out dangerously beyond the periphery of the tank. For this purpose the hoops 10 are provided with inturned ends which are preferably constructed separate and secured thereto, one of the members being shown in perspective at Fig. 2. These inturned ends 11 are seated in chambers 12 formed in the periphery of the stave structure. As shown at Fig. 3, the chambers would be in longitudinal alinement but this of course is wholly immaterial to the construction and some other arrangement of such tension means would possibly increase the strength of the stave structure. Between the inturned extremities 11 a bolt 13 is provided, having a head 14L at one end and a screw threaded portion 15 at the opposite end whereby when the bolt is rotated the extremities 11 are drawn toward each other. When used in conjunction with a rotating tank the chambers 12 receive water or other liquids which by the centrifugal action of the device is thrown outwardly to the annoyance of the operators. To prevent this annoyance, a cover, shown in perspective at Fig. 4, is provided comprising two leaves 16 and 17 hinged together as at 18. The extremities of the leaves 16 and 17 are bifurcated as indicated at Fig. t to produce fingers 19 and 20 respectively which are proportioned to pass through notches or openings 21 formed in the extremity members 11. At Fig. 1, one of these cover members is shown in position which closes the outer side of the chamber 12 to prevent water from being thrown from such chamber when the tank is rotated.

We claim 1. The combination with a tank having a chambered recess formed in its periphery, of a hoop extending about the tank and having inturned rigid extremities disposed within the recess, a tension member disposed within the recess andspanning the interval between the inturned extremities, and a cover member for the recess being substantially flush with the periphery of the tank.

2. The combination with a tank having a chambered recess in its periphery, of a hoop extending about the tank and with its extren'lities located adjacent the w: lls of the recess, hooked members rigidly secured to the extremities of the hoop and turned in In testimony whereof We atfix our signa- Warclly Within the recess, a screw bolt 10- tures in presence of two Witnesses.
